Abstract

A breast implant (1) having a flexible, but impermeable casing (2) and with an electrically conductive filling (3) is provided with an internal electrode (4) and an external electrode (5), with the electrodes being connected to a resistance or impedance measurement device integrated in a transponder (6). In case of perforation of the casing (2), if filling (3) escapes, then the electrical contact between the electrodes (4) and (5) is completed, and a drop in resistance or impedance is registered by the measurement device. In suspicious cases, the implant could be inspected of the measured resistance or impedance values with an external transmitter-receiver unit (13 or 14) and dangerous damage to the breast implant could be determined.

Claims

1. A breast implant (1) for women, comprising a flexible, but impermeable casing (2) and with a filling (3) located in the casing, the implant has an interior in which at least one electrical pole or one electrode (4) is located, and on an outside at least one additional electrical pole or one electrode (5) is provided, the two poles or electrodes are connected to an electrical resistance or impedance measurement device (6), and the filling (3) of the implant is electrically conductive.

2. The breast implant according to claim 1, wherein the two poles or electrodes (4, 5) are connected to a transponder (6) that contains the measurement device and is constructed for the transmission of measurement values to an external receiver (13, 14).

3. The breast implant according to claim 2, wherein the transponder (6) contains a resistor measurement bridge as the measurement device.

4. The breast implant according to claim 1, wherein the electrical pole or the electrode (4) located in the interior of the implant is arranged or fastened on an inner side to a rear wall or back side (7) of the implant as seen in a position of use.

5. The breast implant according to claim 1, wherein the pole or the electrode (5) located on the outside is arranged or fastened on an outer side to the rear wall or back side (7) of the implant as seen in the position of use.

6. The breast implant according to claim 1, wherein the two poles or electrodes (4, 5) are at least one of separated from each other electrically by the casing (2) of the implant or insulated relative to each other.

7. The breast implant according to claim 1, wherein at a position or on a wall holding the outer electrode or the outer pole (5), a recess for the pole or the electrode is provided and the pole or the electrode (5) is countersunk in the position of use relative to a surface of the outer side at least partially or such that the outer side of the pole or the electrode is flush with the outer side of the wall holding it.

8. The breast implant according to claim 2, wherein an opening (8) for introduction of the implant filling and a closure (9) for the opening are provided on a rear wall (7) of the implant and the outer pole or the electrode (5), the transponder (6), and the inner pole or the electrode (4) are arranged on or in the closure (9).

9. The breast implant according to claim 1, wherein lines or electrically conductive arms (10, 11, 12) extend from the pole or electrode and are arranged at least on a rear outer side of a back wall (7) of the implant in a position of use or extend beyond a front side of the implant and are connected to the outer pole or the electrode (5).

10. The breast implant according to claim 1, wherein additional, electrically conductive arms are constructed as elastically deformable, electrically conductive bands.
